Proxi-Repos not working, remain "Online - Ready to Connect"

Sonatype Nexus Repository
, ,
1

Our NEXUS OSS 3.38.0 is running in a K8S Cluster.
All proxy-repositories, even maven-central, remain in the status “Ready to Connect”, although we have tried to retrieve assets from them multiple times.
In the Logfiles is no hint of a malfunction.
Is there annything we have forgotten?

Hi Roland,
What’s the problem you’re facing? Repository status Ready to Connect does not indicate any problem, it’s the contrary, the repository is functioning correctly and is ready to connect to the remote as soon as there will be a need to do so.

3

As I wrote, we have tried to download MULTIPE time various artifacts from these repos.
Even maven-central!
Any request wil respond, as if the repo is empty.

4

Can you attach your request.log and nexus.log, please?

The curl request you’re trying is searching for assets present in your maven-central repository in your Nexus Repository. If you haven’t downloaded any assets yet, it won’t return anything. In other worlds, it’s returning an empty list, because you haven’t cached anything yet - it will not propagate your search query to the remote server.

That was it, thank you very much!
You have to come on it for now.
At least we now have a better understanding of how the proxy works.
Searching in a proxy is not recommended.
Best regards,
roland

I have a similar issue, similar because I don’t have LDAP setup. I’ve setup a Maven2 proxy for remote URL https://repo.maven.apache.org/maven2/, and status is now Online - Remote available, but yet see

I’ve setup my Gradle build.gradle files to access the internal repo, and I see my builds downloading from our other internal repo, but not the above repo. Any clues for me?

buildscript {

          maven {
            url https://nexus.mycompany.com
            credentials {

                password nexusPW
            }
        }
    }
    dependencies {
      classpath "..."
    }
}

    }

I can’t really tell from your description, but check your request.log to ensure that the downloads are trying to go through nexus maybe. If they are getting to nexus but it’s responding with something other than a 2xx response then maybe check your nexus.log for errors. Based on your description I wonder if maybe your build.gradle is mis-configured but I don’t really know.

@mmartz thanks, i will be looking at logs today. I updated my post to include a sample build.gradle that I use.
